FIELD OF THE INVENTION

The present disclosure relates to the construction technology for super high-rise buildings, and more particularly to an integrated formwork system for construction of a super high-rise building.

BACKGROUND OF THE INVENTION

The formwork systems for construction of super high-rise buildings in the world mainly include the DOKA formwork system used by the world's tallest building, i.e. the 828-meter-high Burj Khalifa Tower in Dubai, UAE, which is completed in 2010 and represents the highest level of the current super high-rise building construction; and the world's leading formwork systems commonly used for domestic super high-rise building construction include the integral lifting steel platform formwork system of Shanghai Construction and the large top form formwork system of China State Construction.

The former has the disadvantage that the platform has an insufficient effective load, which cannot meet the requirements of installing spreaders and stacking construction materials.

The latter overcomes the former's disadvantages and can meet the requirements of materials stacking and the arrangement of the spreaders on the platform, and properly improves partial construction effect, but brings new disadvantages: the platform has excessively large deadweight, an excessively high gravity center, a long installation and preparation period, and the installation process takes a long time and generally requires downtime; during jacking operation, the connection between the formwork and the building structure needs to be specially designed and the major structure of the building is required be changed, extending the period of preparation and jacking operation for each jacking of the formwork; and the effective working space of the main working plane is scarce, causing that the construction period is slightly shorter than the former, and reutilization effect is poor, the primary input cost is high, and the comprehensive economic benefit has no outstanding advantage compared with the former.

BRIEF SUMMARY OF THE INVENTION

The technical problems to be solved by the present disclosure are that during the traditional construction of super high-rise buildings, the effective load is insufficient or the platform has the excessively large deadweight, during jacking operation the connection between the formwork and the building structure needs to be specially designed and the major structure of the building is required to be changed, causing the time for the preparation and jacking operation for each formwork jacking to be extremely long, and the insufficient effective working space is unfavourable for construction and causes low efficiency. The present disclosure aims to provide an integrated formwork system for construction of a super high-rise building, which has a better bearing capacity, light deadweight, a low gravity center, better structural safety, a broad construction work plane, shortest preparation time and lifting time for each climbing and highest working efficiency; and compared with the aforementioned systems, the construction period for the construction of the standard floors of the super high-rise building can be shortened by one or more days, and after the construction is completed, the present disclosure can be reused in construction of other super high-rise and ordinary high-rise buildings with only a few changes, having comprehensive economic benefits unmatched by the traditional systems.

The present disclosure is realized through the following technical solutions:

An integrated formwork system for construction of a super high-rise building, comprising a climbing system in a stereoscopic structure formed by a successive enclosure of a plurality of climbing formwork units, wherein a jacking system formed by a plurality of jacking units arranged side by side is disposed in the stereoscopic structure, and a working space for mounting steel structures and steel bars and pouring concrete walls is formed between the climbing system and the jacking system, both the climbing system and the jacking system are capable of moving in a vertical direction, climbing formwork units located at a same side wall of the stereoscopic structure in the plurality of the climbing formwork units all correspond to the jacking units adjacent to the side wall and are capable of moving synchronously or separately, the jacking units are provided thereon with a vertical adjusting device and a horizontal adjusting device respectively positioning position connection points of a vertical position and a horizontal position, and a plurality of groups of tensioning devices for enhancing a structural stability are disposed in each of the jacking units. The world's leading formwork systems commonly used for domestic super high-rise building construction comprise the integral lifting steel platform formwork system of Shanghai Construction and the large top form formwork system of China State Construction, which have following problems during layout at the uppermost three working planes:

1. In addition to the spreaders, the control operation house, the fire water tank and the like are arranged on the top layer; and most construction hoists reach the top layer directly, which significantly reduces the valuable space for working plane and materials stacking in the top layer, and increases the probability of the safety accidents caused by interference and collision as the steel members and materials are lifted into position by the tower crane after the construction hoist reaches the top layer, obviously reducing the effect of lifting large steel members into position.

2. The lower second and third platforms requiring a large number of workers' operations adopt the lifting gangway platform, which has an extremely narrow working space for the workers at work and limits the preparation and use of tools, the working efficiency being low.

3. Since the control operation house is on the top layer, while the working mechanism and the jacking working surface of the jacking operation are at or below the third layer, the electrical control and hydraulic control lines are required to pass through multiple layers of space, complicating protection of the lines in the jacking and working state.

In order to solve the various problems existing in the current construction of the super high-rise building, the platforms of this formwork system adopt an integrated large platform at each layer of a commonly used five-layer operation working surface, allowing each layer to have a large operation space, wherein the specific implementation is as follows:

1. Only the spreaders are installed on the uppermost top layer, the control operation house is installed on the lower third layer which is also the jacking operation layer, and the fire water tank and toolhouse are installed on the lower second layer. To eliminate effects of lifting the large steel members into place, the construction elevator can only reach the layers below the top layer, maximizing the materials stacking capacity of the top layer and ensuring a spacious working space, as shown in FIG. 3.

2. The second working plane layer is convenient to arrange toolboxes for each type of work, the welding machine house and the toolhouse, which can reduce work preparation time and improve working efficiency of the workers working on the platform that has the largest workload, and a 6-ton fire pool is arranged for reliable fire control, as shown in FIG. 4.

3. The third working plane layer is mainly used for preparation and operation control of each jacking operation, and each unit of this layer has an electrical and hydraulic control system, wherein the electrically controlled and hydraulic lines are compactly arranged, not only minimizing the possible damage to the electrically controlled and hydraulic lines during the jacking process and construction, but also facilitating control operations of workers. All the other layers have the large operation space which facilitates the arrangement of the construction machines for each type of work and workers' work and saves a considerable amount of work preparation time, as shown in FIG. 5.

At present, as the building technology advances, people are increasingly advocating super high-rise buildings. Since the formwork of the top form system commonly used in the super high-rise building construction has large deadweight, its gravity center is high during jacking operation, the stability being poor. Also, since the wind at altitude is high, the jacking force is necessary to be further increased to ensure safety of the formwork, thereby increasing the required power of the cylinder and requiring the specialized jacking cylinder and jacking system, which are only applicable for this project and construction site and not universal in other projects and construction sites, having low reutilization and increasing the construction cost. However, the jacking system of this scheme uses a design concept of system general control and standardization plus refinement, which optimizes the forces applied on the system structure, changing from a single point or limited points support to an appropriate multi-point support and satisfying the standardization and assembly requirements, greatly reducing the force applied on each support point, and optimizes the stressed mode of main support components to maximize the reliable resistance of the standard parts and design an integral climbing steel platform jacking system convenient for assembly and maintenance. During jacking operation, such jacking system can jack up to the position at one operation according to its standard floor height, wherein the jack-up height equals to the standard floor height, the gravity center for jacking is low so that the structure is stable and not easily inclined, and jacking up to the position at one operation is simple and efficient and reduces the openings on the concrete wall, not damaging or affecting the wall structure. A support structure of the hydraulic cylinder is composed of a plurality of coaxial cylindrical bodies connected in series, and a seal is formed at junctions of the cylindrical bodies, wherein the lowermost cylindrical body is fixed onto the upper support frame, and the uppermost cylindrical body is fixed onto an operation platform. Guide connecting plates are disposed at the junctions of the cylindrical bodies, each of the junctions has two guide connecting plates, which are symmetrically disposed on and firmly secured to both sides of the cylindrical bodies, wherein the junctions of the cylindrical bodies are located in ranges of the guide connecting plates and connected through high strength bolts. The working stroke of the hydraulic cylinder is determined by satisfaction of the standard floor height of the building, allowing the hydraulic cylinder to jack up to the position at one operation. The solution of one more embedment and one more jacking is used for the special floor so that the adopted hydraulic cylinder has greater universality and can be reused for different construction sites in the future. In order to make the connection of the cylindrical bodies more stable and avoid incline, the guide connecting plates are used to restrict and strengthen the junctions of the cylindrical bodies, meeting the requirements of stress and stability during use.

The lower support frame and the upper support frame are provided with connecting parts, and the connecting parts pass through the corresponding lower support frame or the upper support frame and are connected to the embedded parts in a shear wall. The lower support frame comprises a first horizontal frame which is a rectangular frame with a hollow interior; two first vertical rods in parallel with each other are disposed below the first horizontal frame, wherein a top end of the first vertical rod is vertically fixed onto the first horizontal frame, and both of the first vertical rods are in contact with the sheer wall; the connecting part passes vertically through the first vertical rod and is connected to the embedded part in the shear wall; two first diagonal rods in parallel with each other are disposed between the first horizontal frame and the first vertical rod, wherein two ends of the first diagonal rod are respectively fixed onto the first horizontal frame and one of the two first vertical rods; and the interconnected first vertical rod, first diagonal rod and the first horizontal frame form a right triangle. The upper support frame comprises a second horizontal frame which is a rectangular frame with a hollow interior, wherein the lower support frame is disposed within a range of the end surface of the rectangular frame; two second vertical rods in parallel with each other are disposed below the second horizontal frame, wherein a top end of the second vertical rod is vertically secured to the second horizontal frame, and both of the second vertical rods are in contact with the sheer wall; the connecting part passes vertically through the second vertical rod and is connected to the embedded part in the shear wall; two second diagonal rods in parallel with each other are disposed between the second horizontal frame and the second vertical rod, wherein two ends of the second diagonal rod are respectively secured to the second horizontal frame and one of the two second vertical rods; and the interconnected second vertical rod, second diagonal rod and the second horizontal frame form a right triangle. Mounting plates are fixed both on a top surface of the first horizontal frame and on a top surface of the second horizontal frame, wherein the hydraulic cylinder is fixed onto the mounting plate of the second horizontal frame, and the cylinder pole is fixed onto the mounting plate of the first horizontal frame. A flange connection seat is disposed on the second horizontal frame, and the flange connection seat is fixed onto the mounting plate of the second horizontal frame, wherein a bottom of the hydraulic cylinder is fixed onto the flange connection seat, and a top of the cylinder pole passes through the flange connection seat and is inserted into the hydraulic cylinder. A mounting seat is disposed above the first horizontal frame, wherein the mounting seat is secured to the mounting plate of the first horizontal frame, and a bottom of the cylinder pole is inserted into and secured to the mounting seat. A top surface of the mounting seat is receded to form a mounting groove, wherein the bottom of the cylinder pole is inserted into the mounting groove which has a locking pin therein, wherein the locking pin passes through both the cylinder pole and the mounting seat. Such structural design can greatly increase the stability of the support frames, allowing it to remain to be stable in jacking process and ensuring a safe and reliable jacking process, and the first vertical rods, the first diagonal rods, horizontal frames the second vertical rods and the second diagonal rods are all made of shape steel. After jacked up to the determined position, the loading and unloading processes are also convenient, greatly improving working efficiency.

The particular jacking method of the jacking unit comprises:

The first step: preparation work, checking whether the materials' stacking on each floor meets the design requirements, wherein the materials' stacking should not be too concentrated and exceed the design requirements; and except for the connections between the upper and lower support frames and the building, any other parts (including the formwork) are not connected and interfered with the building.

The second step: firstly removing the connecting parts used to connect the upper support frame and the building, and confirming again that every jacking parts are not interfered with the building.

The third step: actuating the power system to carry out the jacking operation based on the requirements, and keeping eyes on the system pressure and electric until the upper support frame and the entire formwork reach the next connection site and stop.

After confirming that all the connections are firm, the connecting parts of the lower support frame are removed, thereafter the jacking hydraulic cylinder is actuated to make the cylinder pole retract to the connection position of the next layer, and the connecting parts of the lower support frame is connected after the position is reached, so as to complete the jacking operation for one standard floor.

Such jacking method has simple steps capable of jacking up to the position to pass through the standard layer at one operation; the gravity center of the entire jacking process is stable, which transmits the force of the jacking process to the wall through the connecting parts; and since the jacking process is for the standard floor height, the wall of each layer only has the embedded parts corresponding to the connecting parts and no other extra openings, not affecting or damaging the building wall.

At present, during the construction of the super high-rise building, the formwork is reused in each floor, that is to say that in the construction of the building floor, the formwork for the wall of the lower floor is jacked up and moves to the construction site in the upper floor to be reused, reducing the waste of the formwork, wherein the formwork is generally in a plate and bulk structure; and the formwork system for current super high-rise building construction is generally connected to the formwork by manual operation or electric chain hoists and performs lifting operation, since the height difference between the suspension point and the formwork is large, the electric chain hoist should be long enough, wherein the connection is a flexible connection which may cause swinging of the formwork on high floors of the super high-rise building due to the windy condition at altitude, resulting in inaccurate positioning of the formwork reaching in the right position and more adjustments for ensuring the accurate positioning of the formwork, which the latter is time consuming and poorly efficient and requires workers to control the mounting of the formwork according to experiences, which cannot ensure that the formwork rapidly moves to the mounting position, and the swinging caused by the flexible connection may even damage the formwork or hurt the workers. The formwork system designed by this scheme uses a hard connection, which not only realizes fast and accurate positioning, greatly improving the positioning and mounting efficiency, but also enables the formwork to have functions of precise vertical elevation and horizontal positioning through precise adjustments of the vertical and horizontal special adjusting devices, playing a good assistance role in construction measurement and positioning, greatly improving the construction efficiency.

The horizontal adjusting device comprises a horizontal adjusting mechanism, a support plate and an installation plate, wherein a bottom surface of the installation plate is attached to a top surface of the support plate, the support plate is connected to the jacking unit, the horizontal adjusting mechanism is fixed onto a top surface of the installation plate, and the horizontal adjusting mechanism is moveable on the support plate, a positioning wheel in contact with the sheer wall is disposed on the adjusting mechanism, and the horizontal adjusting mechanism is capable of adjusting a position of the positioning wheel to allow a horizontal movement of the positioning wheel. When in super high-rise construction, in view of the bearing capacity and other factors, the internal space is contracted toward the center in a taper or step shape, namely the volume of internal space is gradually reduced, or the wall thickness varies to reduce the self-load of the building structure. The horizontal adjusting mechanism designed by this scheme is installed in the jacking system for contacting the wall surface, and the horizontal position thereof can be adjusted to always press the wall surface reasonably and receive force and to be always in a vertical state, thereby ensuring the working stability of the system and meeting jacking requirements by adjustment according to the change of the internal space during jacking process, the adjustment being convenient and rapid and satisfying the function requirements of structural horizontal positioning and jacking guiding.

The horizontal adjusting mechanism comprises a box body. According to the number of the connecting plates, the positioning wheel can fixed onto the connecting plates in two ways. In a case of one connecting plate, the box body is disposed on the installation plate, wherein a screw-nut pair is disposed in the box body; the connecting plate is disposed outside the box body, wherein one end of the connecting plate is inserted into the box body and is connected to the screw-nut pair, and the connecting plate can move horizontally under action of the screw-nut pair; and the positioning wheel is connected to the connecting plate, wherein the positioning wheel can rotate about its own axis, and a pin shaft is disposed in the positioning wheel, wherein the pin shaft passes through a center of the positioning wheel, one end of the pin shaft is disposed in the connecting plate, and the positioning wheel can rotate about the pin shaft. In order to make the positioning wheel contact the wall to maintain a pressing force, the wheel face of the positioning wheel is disposed outside one end of the connecting plate away from the box body.

In a case of two connecting plates, the box body is disposed on the installation plate, wherein a screw-nut pair is disposed in the box body; the two connecting plates are disposed outside the box body, wherein one end of each of the connecting plates is inserted into the box body and is connected to the screw-nut pair, and the connecting plates can move horizontally under action of the screw-nut pair; and the positioning wheel is disposed between the two connecting plates and connected to the connecting plates, wherein the positioning wheel can rotate about its own axis. A pin shaft is disposed in the positioning wheel, wherein the pin shaft passes through a center of the wheel, two ends thereof are disposed respectively in the connecting plates, and the positioning wheel can rotate about the pin shaft. Similarly, in order to make the positioning wheel contact the wall to maintain a pressing force, the wheel face of the positioning wheel is disposed outside one end of the connecting plates away from the box body; and the screw-nut pair has an existing structure comprising a screw, a nut and a nut seat, wherein the nut is mounted around the screw, the nut seat is installed on the nut, the connecting plates are secured to the nut seat, one end of the screw passes through the box body and is disposed outside one end of the box body away from the wheel, and a lock nut is mounted around a portion of the screw disposed outside the box body. Rotation of the screw drives the connecting plates to move, thereby adjusting the pressed state of the positioning wheel and the wall surface; and in the predetermined position, the lock nut is rotated and secured to the box body to perform locking so that no movement is occurred during operation so as to ensure the working stability of the system.

To further increase stability of the connection, a plurality of screw holes are disposed on the support plate, wherein the plurality of screw holes are divided into two groups, and the centerlines of each group of screw holes are in parallel with each other; the box body is disposed between the two groups of screw holes; and a plurality locking bolts are disposed on the installation plate, wherein all the locking bolts pass through the corresponding screw holes. The number of the locking bolts is four, and they are symmetrically disposed on both sides of the box body. Based on the practical operational experience, four high strength bolts used as the locking bolts can completely meet the fixing requirement; the screw is rotated for fine adjustment, while adjusting the position of the installation plate on the support plate according to actual need is to adjust the thickness of the shear wall in a large range; After a proper position is obtained, the four locking bolts pass through the corresponding screw holes to fix, further stabilizing the system during operation.

The vertical adjusting device comprises a guide track mounted on a jacking frame, wherein the jacking frame is connected to the jacking unit, the guide track can move horizontally on the jacking frame, a guide installation frame capable of moving horizontally along the guide track is installed on the guide track, the guide track is provided therein with a stopper, the stopper is movable and can be fixed in the guide track, and a movement path of the guide installation frame is from the stopper to one end of the guide track away from the stopper. This scheme uses the rigid connection, wherein the suspension point uses the guide track as the suspension and support of the formwork and the formwork is suspended via a hanger at the guide track; only when the thickness of the shear wall changes, the guide track horizontally moves on the jacking frame to a proper position and is fixed; and the stopper is disposed at the end of the guide track to adjust the position of the guide wheel, wherein the positioning stopper is used to adjust the accurate position during the first-time positioning of the formwork, and is fixed on the guide track after the adjustment. After the first-time positioning and construction is completed, the formwork needs no adjustment in its later positioning, and the accurate positioning of the formwork can be realized by moving the wheel suspension structure of the formwork forward until the wheel sliding to the position of the stopper which is adjusted in the first-time positioning, greatly improving the efficiency of positioning and mounting the formwork.

The particular structure of the guide installation frame comprises a wheel and a lifting frame, wherein the wheel is disposed in the guide track and can move horizontally along the guide track, and the lifting frame is disposed under the guide track and connected to the wheel. Thus the wheel is not only used for guiding the movement, but also provides the position limiting function, while the vertical adjustment is realized by a connecting rod which is disposed in the lifting frame, wherein the connecting rod passes through the lifting frame and is located under the guide track, a bottom end of connecting rod passes through a lifting plate connected to a formwork, and the connecting rod can move in the vertical direction; a fine threaded section and a coarse threaded section are disposed on an outer wall of the connecting rod, wherein the fine threaded section is disposed above the coarse threaded section; and the outer wall of the connecting rod is sequentially provided with a fine adjusting nut, a locking nut and a coarse adjusting nut, wherein the lifting frame is disposed between the fine adjusting nut and the locking nut, and the lifting plate is disposed between the locking nut and the coarse adjusting nut. The coarse adjusting nut is used for the coarse adjustment, wherein the vertical distance adjusted by positively or negatively rotating the nut in a full circle is 2.5 mm, the maximum adjustment distance is ±10 cm, and the coarse adjustment preliminarily adjust the error between the distance and the standard value within ±3 cm; and the fine adjusting nut is used for the fine adjustment. The coarse adjustment is generally used during the installation, and due to the compactness of the overall structure, the fine adjustment can meet the most of the requirements as long as the wall body is unchanged.

Actually, according to the materials availability of the program, the guide track is usually formed by i-steel or channel steel. In a case of the guide track being the i-steel, two wheels and two stoppers are used, wherein one wheel and one stopper are correspondingly disposed in one inner cavity of the i-steel, while the other wheel and the other stopper are correspondingly disposed in the other inner cavity of the i-steel, and can move along the inner cavities of the i-steel. In a case of the guide track being the channel steel, two pieces of channel steel are connected by welding or bolts to form an integral structure with their openings being remote from each other; and two wheels and two stoppers are used, wherein one wheel and one stopper are correspondingly disposed in the inner cavity of one piece of channel steel, while the other wheel and the other stopper are correspondingly disposed in the inner cavity of the other piece of the channel steel, and can move along the inner cavity of the channel steel. The cross-section of the lifting frame is U-shaped, the wheels and the guide track are all disposed in the cavity of the lifting frame, wherein the wheels correspond to the lifting frame and can rotate about their own axes, and the lifting frame is provided thereon with a connecting bolt which passes through the lifting frame and is secured to the formwork. In this way, the fixing for lifting the formwork is realized, and the two groups of wheels make the movement more balanced and safer.

A strip through hole is disposed on the stopper, wherein a locking pin is disposed in the strip through hole, the locking pin passes through both the strip through hole and the guide track, and the locking pin is movable in the strip through hole. The stopper is preferably made of angle steel, wherein the positioning stopper is used to adjust the accurate position during the first-time positioning of the formwork, and is fixed on the guide track though such high strength bolts of the locking pins after the adjustment; and after the first-time positioning and construction is completed, the formwork needs no adjustment in its later positioning, and the accurate positioning of the formwork can be realized by moving the wheel suspension structure of the formwork forward until the wheel sliding to the position of the stopper which is adjusted in the first-time positioning, greatly improving the efficiency of positioning and mounting the formwork.

For the position where the thickness of the shear wall that is being poured changes, a plurality of connecting holes varying with the shear wall thickness are processed and formed in advance on the guide track formed by one piece of i-steel or the combination of two pieces of channel steel, wherein the same shear wall thickness corresponds to the corresponding connecting hole, and the connecting hole is provided therein with a locking bolt which passes through the connecting hole and is connected to the lifting frame, thus realizing fast and accurate positioning of the formwork when the thickness of the shear wall varies.

The tensioning device comprises a tensioning rod, wherein the tensioning rod is disposed between operation platforms adjacent thereto, and two ends of the tensioning rod are respectively connected to the corresponding operation platform, wherein a vertical rod is disposed between adjacent operation platforms, two ends of the vertical rod are respectively fixed onto the corresponding operation platform, and the vertical rod is disposed between the tensioning rods located between the floors. In the traditional construction of super high-rise building, various materials and equipment are placed on the operation platform to perform fast construction and preparation; although the weight of these items is within the load-bearing limits of the jacking equipment, the load is still increased by these items which are necessary for construction and cannot be discarded, increasing internal stress of the jacking structure, affecting service life, and causing hidden danger to the system stability after a long period of use. In the structure designed by this scheme, several tensioning rods are used in conjunction with the vertical rods to perform adjustment according to the load situation of the operation platform, which reasonably distributes the load, thereby increasing the stability of the system structure, reducing the deadweight of the structure, facilitating reutilization, and greatly reducing the cost.

Generally, several layers of the important operation platform are required, wherein two tensioning rods are disposed between any two adjacent operation platforms, all tensioning rods form an X-shaped structure, and such structure formed by tensioning rods can achieve the optimum bearing capacity, improving the system stability. The vertical rod is disposed between the two tensioning rods disposed between the adjacent operation platforms, and the two ends of the vertical rod are vertically secured to the corresponding operation platform respectively. The uppermost operation platform is used as the main stacking layer, so the force is the largest, and with the support of the vertical rods disposed below, the load can be effectively and reasonably dispersed.

A bottom surface of the uppermost operation platform, a top surface of the lowermost operation platform and a middle layer operation platform of the operation platforms are all provided with two positioning plates, wherein the vertical rod is disposed between the positioning plates, two ends of the two positioning plates of the middle layer operation platform both pass through this operation platform and are respectively disposed between the uppermost operation platform and the middle layer operation platform, and between the middle layer operation platform and the lowermost operation platform, and one end of each of the tensioning rods is connected to one end of the corresponding positioning plate. An adjusting bolt is mounted on the one end of the tensioning rod, wherein the adjusting bolts of the tensioning rods located between the uppermost operation platform and the middle layer operation platform are all connected to the positioning plates disposed on the bottom surface of the uppermost operation platform, and the adjusting bolts of these tensioning rods can rotate about the connection points of adjusting bolts and the positioning plates connected thereto. The adjusting bolts of the tensioning rods located between the middle layer operation platform and the lowermost operation platform are connected to the bottom of the positioning plates passing through the middle layer operation platform, and the adjusting bolts can rotate about connection points of adjusting bolts and the positioning plate connected thereto. Connecting pins are disposed respectively between the positioning plate and the tensioning rod, and between the positioning plate and the adjusting bolt, wherein the connecting pins pass through both the corresponding positioning plate and the tensioning rod or the adjusting bolt, and the adjusting bolt s of these tensioning rods can rotate about an axis of the corresponding connecting pins. The positioning plates on the uppermost operation platform, the positioning plates on the middle layer operation platform and the positioning plates on the lowermost operation platform are all symmetrical along the midline of the vertical rod. By adjusting the adjusting bolts, the tensioning rods can be tensioned at different angles and different lengths, meeting the stress requirement of the rods, and increasing the structural stability of the system.

Since the uppermost operation platform is used as the main stacking layer and bears the largest force, the thickness of the middle layer operation platform and the thickness of the lowermost operation platform are smaller than the thickness of the uppermost operation platform. The middle layer operation platform and the lowermost operation platform have less stacked materials thereon, and are not required to bear excessive force, thus their thicknesses need not to be too thick so as to reduce the weight of the entire system.

When the jacking operation is carried out, the upper support frame 7 or the lower support frame 11 can be independently used as the fulcrum to realize the corresponding jacking operation, which can jack up to the determined position at one operation. Also, such structure requires small jacking space, and can reasonably distribute the jacking force, allowing that the existing ordinary hydraulic cylinder can be used as the jacking cylinder, facilitating assembly and maintenance, and reducing cost.

The number and length of the cylindrical bodies are set in view of the commonly used modulus for the actual floor height of the high-rise buildings, and the working stroke of the hydraulic cylinder is determined by satisfaction of the standard floor height of the building, allowing the hydraulic cylinder to jack up to the position at one operation. One more embodiment and one more jacking are used for the special floor so that the adopted hydraulic cylinder has greater universality and can be reused for different construction sites in the future. A square opening is disposed on the hydraulic cylinder for its easy replacement as accidents occur. The basic modulus of the hydraulic cylinder and the bearing structure thereof uses 3-meter height, and the present implementation project increases the height to 4.5 meters according to the modulus, wherein the standard floor height for the specific and pertinent project is increased according to the series of preferred numbers principle, allowing the whole system to meet construction requirements of almost all the high-rise buildings, and maximizing utilization efficiency of all structural members and key hydraulic parts.

Mounting plates are fixed both on a top surface of the first horizontal frame and on a top surface of the second horizontal frame, wherein the hydraulic cylinder 3 is fixed onto the upper mounting plate 39 of the second horizontal frame, and the cylinder pole 8 is fixed onto the lower mounting plate 14 of the first horizontal frame. A flange connection seat 5 is disposed on the second horizontal frame, and the flange connection seat 5 is fixed onto the upper mounting plate 39 of the second horizontal frame, wherein a bottom of the hydraulic cylinder 3 is fixed onto the flange connection seat 5, and a top of the cylinder pole 8 passes through the flange connection seat 5 and is inserted into the hydraulic cylinder 3. A mounting seat 13 is disposed above the first horizontal frame, wherein the mounting seat 13 is secured to the lower mounting plate 14 of the first horizontal frame, and a bottom of the cylinder pole 8 is inserted into and secured to the mounting seat 13.

All the mounting plates use rectangular square steel, wherein the lower mounting plate 39 uses one piece of rectangular square steel for the gripping of the flange connection seat 5, and the upper mounting plate 39 uses two pieces of rectangular square steel for cylinder pole 8 to pass through. The size of the upper support frame 7 is larger than that of the lower support frame 11, wherein the upper support frame 7 can be regarded as two right triangles from a side view in section along the vertical direction, and the lower support frame 11 and the cylinder pole 8 are capable of travelling between the two right triangles to perform jacking operation; in order to further improve stability, a plurality of ribbed plates are disposed in the lower support frame 11, the ribbed plates connecting two right triangles of the lower support frame 11 to further stabilize the structure; and each right triangle of the upper support frame 7 and each right triangle of the lower support frame 11 are provided therein with a plurality of ribbed plates for connection so that they are divided into multiple small triangles, further enhancing the stability. Through such design, the structure of the support frames can ensure the stability during use, and simplify the overall structure while the support requirements are met, simplifying the operation processes; and the jacking support structure can efficiently overcome the disadvantages of the existing formwork system, and have a good bearing capacity, light deadweight, reliable connection and simple operation. Every support frame adopts space triangular truss structure, which has the easily analyzed force and a quite high bearing capacity, and can withstand a vertical load of 80 tons at a single point.

The design of the present disclosure adopts the reverse thinking, which first determine the number n (n=P/F, P-total load of the unit) of the support points according to the greatest bearing capacity F of the mature and reliable jacking cylinder commonly used on the market. Nanning Huarun east office building is taken as an example: the core tube is divided into six modules, wherein the largest module unit has deadweight of 100 tons, various live loads of 80 tons, and the most unfavorable effect design value is set as 240 tons; and since the greatest bearing capacity of the mature and reliable jacking cylinder commonly used on the market is 80 tons (cylinder diameter of 150 mm), the number of the support points n=240/80=3, each module using four jacking cylinders.

The control system also uses the same design thinking to choose the most mature and reliable hydraulic control system on the market (the nominal pressure p of the system meets requirement of the greatest bearing capacity F of the hydraulic cylinder, p=F/S, and S-area of the hydraulic cylinder), which takes Nanning Huarun east office building as an example: the required nominal pressure of the system is: p=800000/70650=11.4 Mpa, wherein the alternative system pressure according to availability on the market comprises 15 Mpa, 20 Mpa, 25 Mpa, 30 Mpa and 35 Mpa, and the system having nominal pressure of 25 MPA is selected through economic comparison, which can not only ensures enough system pressure and safety but also has good economy.

Moreover, the hydraulic cylinder is placed in the middle of the two pieces of channel steel, facilitating protection of the hydraulic cylinder, and causing no collision damage to the cylinder due to accidents during working or transportation.

The basic modulus of the hydraulic cylinder and the bearing structure thereof uses 3-meter height, allowing the whole system to meet the construction requirements of almost all the high-rise buildings, wherein the standard floor height for the specific and pertinent project is increased according to the series of preferred numbers principle (e.g. the total height for Nanning Huarun east office building is designed as 5 meters), maximizing utilization efficiency of all structural members and key hydraulic parts.

The connection between the hydraulic cylinder and the support structure uses hinge pin connection, improving efficiency of installation and removal, and a square opening is provided on a top of the bearing structure of the hydraulic cylinder, leaving replacing space for replacing the hydraulic cylinder in some accidental conditions, which facilitates the replacement of the hydraulic cylinders as the accidental damage occurs, without affecting the construction period.

Example 3

As shown in FIG. 10. FIG. 11 and FIG. 12, based on the aforementioned examples, since two adjusting conditions are required during jacking operation, this scheme has two adjustment functions, wherein one realizes adjustment in a large range by moving the horizontal adjusting mechanism on the support plate 37, which is generally used when the inside of the jacking space changes; and the other is to adjust the positioning wheel 33 to move horizontally, mainly used for the uneven wall, to maintain the pressed state against the wall surface and bear force, thereby avoiding tilt. Such system has the function of simultaneous adjustments in a large range and in a small range, ensuring the stability of the system during jacking operation.

When in use, according to the range to be adjusted, the adjustment within a large range is performed first, wherein the installation plate 39 is moved to the position of the support plate 37, after reaching the correct position, four high strength bolts are inserted into the corresponding screw holes to form fixing, thereafter the screw 34 is rotated to move the connecting plate 35 so that the positioning wheel 33 is pressed against the wall surface; in order to enable the positioning wheel 33 to contact the wall so as to maintain pressing force, the wheel face of the positioning wheel 33 is disposed outside one end of the connecting plate 35 away from the box body 38, thereafter the lock nut 36 is rotated so that it is pressed against a wall surface of the box body 38, achieving the fixing of the position of the screw 34, avoiding the movement during work which may deteriorate the stability and cause tilt.

In a case of two connecting plates 35, the manner that the positioning wheel is disposed between the connecting plates 35 further improves the stability of the positioning wheel 33, produces no deformation, and stabilizes the force in pressed state.

In actual use, a plurality of the present disclosures are used together to achieve multipoint contact and press against the wall surface according to the changes of the thickness or flatness of the wall, causing the system to maintain the vertical state, and every point thereof receiving stress to avoid tilt, resulting in better stability.

The vertical adjusting device comprises a guide track 50 mounted on a jacking frame, wherein the jacking frame is connected to the jacking unit, the guide track 50 can move horizontally on the jacking frame, and a guide installation frame capable of moving horizontally along the guide track 50 is installed on the guide track. The suspension structure of the existing formwork is generally connected to the formwork by manual operation or electric chain hoists, since the height difference between the suspension point and the formwork is large, the electric chain hoist should be long enough, such flexible connection causes inaccurate positioning of the formwork reaching in the correct position and more adjustments for ensuring the accurate positioning of the formwork, which the latter waste considerable amount of installation and preparation time, the working efficiency being poor. However, the suspension structure of the formwork designed by this scheme has a small height difference between the suspension point and formwork, and uses the rigid connection, wherein the suspension point uses the guide track 50 as the suspension and support of the formwork, the formwork is suspended via the guide installation frame at the guide track 50; and the stopper is disposed at the end of the guide track 50 to adjust the position of the wheel, wherein the accurate positioning is performed during the first-time positioning of the formwork, and its position is adjusted by the positioning stopper, and the positioning stopper is fixed on the guide track 50 after the adjustment. After the first-time positioning and construction is completed, the formwork needs no adjustment in its later positioning, and the accurate positioning of the formwork can be realized by sliding the guide installation frame of the formwork forward to the position of the stopper which is adjusted in the first-time positioning, greatly improving the efficiency of positioning and mounting the formwork. The adjustment sequence is that, first the horizontal position of the guide track 50 on the jacking frame is adjusted when the thickness of the shear wall changes, then the position of the stopper relative to the guide track 50 is adjusted, and finally the position of the guide installation frame relative to the guide track 50 is adjusted, realizing the adjustment in a stepwise manner and according to the actual needs, improving the installation efficiency.

The guide installation frame is divided into a wheel 40 and a lifting frame 42, wherein the wheel 40 is disposed in the guide track 50 and can move horizontally along the guide track 50, and the lifting frame 42 is disposed under the guide track 50 and connected to the wheel 40. The cross-section of the lifting frame 42 is preferably U-shaped to improve stability when the formwork is suspended; and the wheels 40 and the guide track 50 are all disposed in the cavity of the lifting frame 42, wherein a connecting shaft 41 is disposed in the wheel 40, the connecting shaft 41 passes through a center of the wheel 40 and is connected to the lifting frame 42, and the wheel can rotate about an axis of the connecting shaft 41. A connecting rod 44 is disposed in the lifting frame 42, wherein the connecting rod 44 passes through the center of the lifting frame 42 and is located under the guide track 50, a bottom end of connecting rod 44 passes through a lifting plate 47 connected to the formwork 31, and the connecting rod 44 can move in the vertical direction.

The guide track 50 can be formed by two different materials, and the first one using the i-steel comprises two wheels 40, wherein one wheel 40 is disposed in one inner cavity of the i-steel, while the other wheel 40 is disposed in the other inner cavity of the i-steel, and can move along the inner cavities of the i-steel; the material of the i-steel is obtained at the construction site, or the abandoned i-steel at the construction site can be used; and the inner cavities formed symmetrically on both sides are used to place the wheels 40 and stoppers, capable of ensuring stability during movement. The second one uses channel steel, wherein two pieces of channel steel are connected by welding or bolts to form an integral structure with their openings being remote from each other, and two wheels are used, wherein one wheel 40 is disposed in the inner cavity of one piece of channel steel, while the other wheel 40 is disposed in the inner cavity of the other piece of the channel steel, and can move along the inner cavity of the channel steel. The material of the channel steel is obtained at the construction site, or the abandoned channel steel at the construction site can be used; and the two pieces of channel steel are welded with their openings being opposite one another, allowing wheel 40 to respectively move in one piece of the channel steel, wherein their channel depth facilitates firm clamping of the wheel and the wheel is less likely to fall off, capable of ensuring stability during movement.

the guide track 50 is provided therein with a stopper, and the stopper is movable and can be fixed in the guide track 50, wherein a movement path of the guide installation frame is from the stopper to one end of the guide track 50 away from the stopper; and a strip through hole is disposed on the stopper, wherein a locking pin is disposed in the strip through hole, the locking pin passes through both the strip through hole and the guide track 50, and the locking pin is movable in the strip through hole. The stopper made of angle steel is generally disposed at ends of the support frame, which can adjust the position of the wheel; and the accurate position can be adjusted by the positioning stopper during the first-time positioning of the formwork, and the poisoning stopper is fixed on the guide track 50 though such high strength bolts of the locking pins after the adjustment. After the first-time positioning and construction is completed, the formwork needs no adjustment in its later positioning, and the accurate positioning of the formwork can be realized by moving the wheel suspension structure of the formwork forward until the wheel sliding to the position of the stopper which is adjusted in the first-time positioning, greatly improving the efficiency of positioning and mounting the formwork. For the position where the thickness of the shear wall that is being poured changes, a plurality of connecting holes varying with the shear wall thickness are processed and formed in advance on the guide track formed by one piece of i-steel or the combination of two pieces of channel steel, while the lifting frame is also provided with connecting holes, wherein such connecting holes correspond the same shear wall thickness, and the number of such connecting holes is less than connecting holes on the guide track; the guide track 50 horizontally moves relative to the jacking frame and is fixed in the correct position; and the connecting hole is provided therein with a locking bolt which passes through the connecting hole and is connected to the lifting frame, thus realizing fast and accurate positioning of the formwork when the thickness of the shear wall varies.

The particular adjustment method designed by the present disclosure comprises:

(1) using M20 connecting rod 44 to connect the formwork and the suspension point, wherein the upper end of the rigid connecting rod 44 is the M20×1 high-precision fine thread, the lower end is the M20×2.5 ordinary coarse thread, and both of the upper and lower ends of the connecting 44 have a pair of adjusting and locking nuts;

(2) for the formwork 2 having jacking installation connecting holes, according to the designed installation dimension of the M36 connecting bolts on the upper and lower support seats, after the formwork 12 being manufactured, performing aging treatment until the internal stress being completely released, transporting to the mechanical processing plant and using boring machine to perform processing according to the designed installation dimension, wherein the dimensional precision is controlled within ±0.1 millimeters, allowing the installation of the formwork to meet the first step requirement of the precise positioning; and

(3) during the first installation and commissioning of the formwork, performing two-step adjustment on the vertical elevation:

The first step of the adjustment: adjusting the vertical elevation position by the M20×2.5 ordinary coarse thread on the lower end of the rigid connecting rod, wherein the vertical distance adjusted by positively or negatively rotating the nut in a full circle is 2.5 mm, the maximum adjustment distance is ±10 cm, the error with the standard value is preliminarily adjusted to within ±3 cm, then the locking bolts are used to lock so as to avoid changes of distance.

The second step of the adjustment: measuring the vertical elevation and precisely measuring the difference with the designed standard value, wherein the difference requiring second adjustment is adjusted by high-precision fine thread with the upper end of M20×1; the nut is adjusted by the special and scaled socket wrench 49, wherein the range over one circumference of 360 degrees on the socket is equally divided into 10 scales, each rotation of one scale relative to the adjusted reference point causes the vertical elevation to produce a precise change of 0.1 mm (the 10 scales within the range of 360 degrees produce the vertical elevation change of 1 millimeter in total), and the high-precision fine thread with the upper end of M20×1 is adjusted to achieve vertical precise positioning, wherein the adjustment range is from 0 to ±3 millimeters; The precision of the vertical elevation position can be controlled within ±0.1 millimeters with the scaled socket (thereby effectively realizing precise control of the vertical elevation), and after adjustment the locking bolts are used to lock so as to avoid changes of distance.

During the first installation and commissioning of the formwork, the horizontal displacement is adjusted as follows:

Measuring the position in the horizontal direction, recording the measured difference, using the adjusting bolts on the adjusting wheel parallel to the suspended formwork to perform adjustment, wherein the adjusting wheels are disposed on the four support surfaces of the shear wall, and each time using the adjusting bolts on the adjusting wheel parallel to the suspended formwork to perform adjustment, achieving objective of precisely controlling the horizontal position.

After the first installation, measurement and commissioning of the formwork are completed, and M36 positioning embedded parts are installed at the positioning points of the formwork. Then the installation of the formwork is carried out, thereafter the construction for one standard floor is completed since the concrete pouring is finished.

After the first construction of the standard floor is completed, each construction and adjustment for subsequent standard floor only need to perform a test at first; since the present formwork system has a reliable vertical anti-tilt equipment, in each normal jacking state, the horizontal positions may not change and no adjustment is required (the changes caused by construction accident can be adjusted according to the adjustment method of the horizontal displacement in the first installation). After the test of the vertical elevation, according to the error value, at most one step of vertical precise adjustment is performed, greatly improving the construction efficiency of the formwork in subsequent each standard floor.

In the construction of the project in Nanning, during the subsequent construction process of each standard floor, the position deviations in the vertical and horizontal directions in each measurement are extremely small, and one adjustment on the horizontal and vertical positioning is necessary after the construction of ten standard floors, indeed realizing the function of precisely positioning the vertical elevation and horizontal position, and playing a good assistance role in construction measurement and positioning, greatly improving the construction efficiency. The present disclosure effectively overcomes the disadvantages of the traditional chain hoists that the accuracy of connection and positioning is not high, many adjustments are required in each accurate positioning of the formwork, time consuming and low construction efficiency.

When in tensioning adjustment, the adjusting bolts 29 of the tensioning rods 23 located between the uppermost operation platform 25 and the middle layer operation platform 22 are adjusted first, then the adjusting bolts 29 of the tensioning rods 23 located between the middle layer operation platform 22 and the lowermost operation platform 26 are adjusted, such sequence can increase the structural stability of the system, wherein the uppermost operation platform 25 is the primary force-bearing layer, whose force is dispersed through the tensioning rods 23, and the adjusting bolts 29 are adjusted to adjust the tensioned state of the tensioning rods 23, allowing the tensioning rods 23 to rotate about the connecting pins 28 via the adjusting bolts 29, thereby changing their lengths and angles, eventually tensioning the tensioning rods 23 to obtain reasonable distribution and load bearing, finally achieving a most stable state. The designed adjustable formwork structure provided herein improves the structural stability of the jacking system and reduces the deadweight of the structure. Since the uppermost operation platform 25 is the primary bearing layer, the thickness of the uppermost operation platform 25 is larger than the thickness of the middle layer operation platform 22 and the thickness of the lowermost operation platform 26.

In order to have the construction elevator reach the working surface of the platform, a platform connecting structure is further provided, the particular structure being not shown in the drawings, and comprises a support frame secured to the bottom surface of the working platform, wherein a plurality of guide devices are disposed in the support frame, the elevator frame passes through the inside of the support frame and simultaneously approaches all the guide devices, and the guide devices move along the outer wall of the elevator frame when they move with working platform. For the existing construction elevator according to the conventional design, as the number and the height of the construction floors increase, the time for each increase of the elevator height is prolonged, causing that the constructors cannot reach the top form working surface within at least half a day, wasting the waiting time. Although the improved formwork is able to be connected to the standard sections, allowing the fast installation of the standard sections and ensuring safe operation of the construction elevator, the formwork itself is troublesome to be manufactured and installed and has a high cost. This scheme fixes the support frame onto the bottom surface of the working platform, wherein the plurality of guide devices are disposed in the support frame, the elevator frame passes through the inside of the support frame and simultaneously approaches all the guide devices, and in the process of the guide devices moving with the working platform, they move along the outer wall of the elevator frame. With such structure, as the number of the standard sections of the construction elevator increases, the guide devices always move along the surface of the standard sections, changing the cantilevered end of the construction elevator into a slide bearing, and doubling the cantilever length of the construction elevator; after each jacking operation of the top form is completed, the slide bearing still maintain the sliding support for the standard sections of the elevator, so that the elevator can be put into use in time, that is to say the operators may not affect the use of the elevator during the jacking process of the top form.

In order to ensure the uniformity of the force and safety, the guide devices is preferably arranged symmetrically, namely each guide device and another guide device in the guide devices are respectively arranged symmetrically along the center of the elevator frame.

The guide devices have two types of particular structures, wherein one type is that each guide device in the guide devices comprise a guide wheel and an installation plate, wherein the installation plate is vertically fixed onto the inner wall of the support frame, and the guide wheel is provided with a pin shaft, wherein the pin shaft passes through a center of the guide wheel and is connected to the installation plate, the guide wheel can rotate about the pin shaft, and the wheel face of the guide wheel approaches to the outer wall of the main pipe of the elevator frame. The other type is that each guide device in the guide devices comprises a guide wheel and two installation plates, wherein the installation plates of the same guide device are parallel with each other and are vertically fixed onto the same inner wall of the support frame, and the guide wheel is disposed between the two installation plates of the same guide device and is provided with a pin shaft, wherein the pin shaft passes through the center of the guide wheel and the two ends thereof are respectively secured to the installation plates, the guide wheel can rotate about the pin shaft, and the wheel face of the guide wheel approaches the outer wall of the main pipe of the elevator frame. Selection is performed according to the actual needs.

The clearance between the wheel face of the guide wheel and the outer wall of the main pipe of the elevator frame is preferably 0.5 mm. Such clearance can realize a precise engagement, allowing the elevator standard sections can still be reliably supported after the completion of the jacking operation of the top form. The guide devices comprise two guide devices approaching to the outer wall of the same main pipe, wherein the guide wheels of the two guide devices are vertically disposed. Thus one main pipe is operated under clamping of two guide wheels, and its operation can be kept consistent, the movement stability being higher. Four high strength bolts are disposed at each connection of the support frame and the platform, while all the high strength bolts are connected both to the support frame and the working platform, and can also be connected through the pin shafts, and the particular way is set according to specific construction conditions, as long as the fixing between the support frame and the working platform is stable.

Its particular connecting method comprises:

The first step: completing the preparation, installing the attachment devices between the top construction elevator and the major structure of building in advance;

The second step: opening the top cap at the standard section of top construction elevator, having the elevator standard section that is to be jacked up to the same height as the top form pass through the top cap and be connected to the former elevator frame, meanwhile, checking whether the clearance between the slide bearing wheel and the standard section of the construction elevator is within 0.5 millimeters, and ensuring the wheel can rotate flexibly;

The third step: performing the jacking operation of the top form in accordance with the standard procedure for the jacking operation of the top form;

The fourth step: after the jacking operation of the top form being completed, checking whether frame wheel and the standard section of the construction elevator are reliably supported, and checking whether the clearance between them is within 0.5 millimeters, closing the top cap after checking, and the construction elevator being able to be put into normal operation; and

The fifth step: after each jacking operation of the top form being completed, the construction elevator being able to be put into operation simultaneously.

In order to adjust the assembly clearances of inner and outer formworks in a large area, the quick-fit structure is designed, the particular structure being not shown in the drawings, and comprises a rectangular elevator shaft formed by walls formed by sequential arrangement of a plurality of formworks and corner formworks, wherein the corner formworks are disposed at the corner of the walls; second positioning plates are disposed on the formworks and on the corner formworks, and a guide connecting plate is disposed between the second positioning plates, wherein the guide connecting plates between the adjacent formworks are all connected to the second positioning plates; and a lapping plate is disposed on each corner formwork located at the junction of the corners of the walls, wherein the lapping plate also attached to the formwork located at the same place. In the construction, especially in nowadays' reinforced concrete poring forming construction, the formworks are required to be set up in advance to facilitate pouring and forming of the concrete; however when the concrete is poured, the pressing force may easily cause the formworks to move, hence the formworks need to be fixed firmly to each other; however during removal of the formworks, such complicated fixing manner may cause troublesome removal of the formworks, affecting the conduction period. Meanwhile, after the concrete is poured, the formworks may inevitably move, but even the displacement occurs during pouring, the prior art takes no measures until the concrete is dry, the concrete easily leaking from the clearance, thereby affecting the quality of the walls. The structure designed by this scheme has a simple structure and fast and convenient assembly in precondition of guaranteeing the fixing of the formworks, and can adjust the clearances, thereby using lapping plates to timely and automatically adjust the clearances caused by any possible displacement during pouring of the concrete, ensuring that the clearances may not be produced in the process of pouring concrete, effectively avoiding leakage of the concrete, and ensuring the quality of the walls.

When in practical use, a portion of the lapping plate is curved into an arc shape, wherein the opening of the arc shape faces to the outside of the elevator shaft, it is connected to the corner formwork of the wall at the corner area, and is attached to the outer wall of another formwork next to the wall; in fact, the lapping plate is disposed on the side of the formwork facing the concrete, and its top of the arc faces the concrete; thus the pressing force of the concrete against the lapping plate faces the lapped formwork when adjusting, and the lapping plate is pressed by the pressing force received by the lapping plate and attached to the connected formwork; due to the assembly of multiple formworks, and for ensuring the complete coverage of the clearance adjusting range, the length of the lapping plate is the same as the length required by the formworks, and the width of the lapping plate depends on the particular clearance adjusting range (generally being 0-50 millimeters).

To ensure the firmness of the connections of the formworks, each formwork has two second positioning plates parallel with each other, and the guide connecting plate is disposed between the two second positioning plates. The second positioning plates are preferably the channel steel, their notches are disposed away from each other, and the number of the guide connecting plates is two and the two guide connecting plates are parallel with each other. As the construction proceeds, some concrete blocks are inevitably stuck to the surface of the positioning plates; if the positioning plates are connected directly without the guide connecting plates, their uneven surfaces cannot be in close connection, causing clearances and affecting the quality of concrete pouring; and after the positioning plates are set, the length of the positioning plates is set along the full width of the formwork, and the guide connecting plates are relatively short which is convenient for smoothing the surface, thus the guide connecting plates can be rapidly attached to the positioning plates to form the relatively firm fixing.

The connecting plates are also provided with a taper pin, wherein the taper pin passes both the connecting plate and the positioning plate, a plurality of locking holes are disposed on the positioning plate, four through holes are disposed on the guide connecting plates, and the taper pins pass through the four through holes and are inserted into the corresponding locking holes. The taper pin itself is easy to obtain, and has self-locking function, which enables the guide connecting plates and the positioning plates to realize quite smooth surface attachment; meanwhile, when the displacement is adjusted during the first assembly of the formwork, the taper pin can be unfastened in time to select a correct position to fix; at last, the tapping plates are used to realize the complete coverage of the possible adjusting range of the clearances, guaranteeing the forming quality of the walls. Two pin holes are defined on the taper pin, wherein the distance between the two pin holes is larger than the distance between the positioning plates, and a pin shaft is inserted into the pin holes to fix the taper pin after the insertion of the taper pin.

In the present disclosure, a highly reliable formwork tie structure in construction of the shear walls of the large space and super high-rise buildings is also provided, such structure being not shown in the drawings, and comprises a plurality groups of support formworks parallel with each other, a plurality of groups of support frameworks disposed between the adjacent support formworks of the plurality groups of support formworks, wherein the support frameworks are respectively connected to their adjacent support formworks, and a tensioning device disposed on the support formwork, wherein the tensioning device passes through all the support formworks and is fixed onto the outermost support formwork. In current construction of the buildings, the use of the tie rod for formworks is a very common technology, wherein the interval of the tie bars of the existing formwork is generally 600-800 mm; since various types of shape steel formed mainly by assembly welding of large steel plates are used as the major load-bearing members in the shear walls of the super high-rise buildings, and each member being relatively large, wherein section is 1000 mm or more; due to the limitation of the structure and technology, in order to ensure the safety and force stability of the construction, the intervals of the tie bars of the currently used formworks are generally 600-800 mm, which causes the cross-pulling connecting rod for the tie position of the formwork to be required to pass through the shape steel formed by assembly welding of the steel plates, so that the borehole treatment is necessary to be performed at each tie position to be passed through, which is time consuming, and may also damage the shape steel. This scheme changes the stress structure, saves the expense of steel through the support framework, and improves the support stiffness of the large formworks, allowing the maximum support spacing of the tie bars to reach 1200 mm under the condition of the designed large formworks completely satisfying the stiffness and strength, and fixing and tying the formwork without the borehole treatment performing on any shape steel in the shear wall, having extremely high efficiency in cross-pulling connection of the formworks.

The support frame is preferably the unequal angle steel, wherein the long side of the angle steel is perpendicular to the support formwork, the short side is parallel with the support formwork, and all the short sides of the unequal angle steel are preferably remote from the center of the structure formed by the support formworks. The dimension of the unequal angle steel is designed to be 80*50*5 mm. Through the experiment, the long side being 80 of the unequal angle steel is as the main forced direction, thus not only making the major support formworks save the expense of steel by 26%, but also increasing the support stiffness of the large formworks by 60%, allowing the maximum support spacing of the tie bars to reach 1200 mm under the condition of the large formworks designed by us completely satisfying the stiffness and strength, and fixing and tying the formwork without the borehole treatment performing on any shape steel in the shear wall, having extremely high efficiency in cross-pulling connection of the formworks.

In order to improve the stability of the overall formwork structure, a back ridge is disposed on the outermost support formwork of the support formworks, and the back ridge is fixed onto this support formwork; and a tensioning device passes through the back ridge and is fixed onto the back ridge. The tensioning device is preferably a combination of a tie rod and a locking nut, wherein the tie rod passes through all the support formworks and the back ridge, and the locking nut is mounted around the tie rod and in contact with the surface of the back ridge away from the support formwork. The fitting manner of the tie rod and the locking nut is a structure commonly used in the construction site, which facilitates installation and removal and reduces the use cost, and guarantees the tensioning quality; through experiments, the distance between the adjacent tie rods of the tie rods being larger than 1000 mm is able to meet the use requirements, thereby completely avoiding the shape steel so that no holes being defined on the shape steel, ensuring completeness of the shape steel and satisfying the stiffness and strength of the shape steel; and due to lack of intermediate processing, the waiting time is reduced, greatly shortening the construction period.

The examples described above, further illustrate the purposes, technical solutions and beneficial effects of the present disclosure. It is to be understood that the foregoing is only the examples of the present disclosure, and is not intended to limit the protective scope of the present disclosure.
